Ultimaker 2 intermediate layer issues

Recommended Posts

Hello guys,

This is my first post here and unfortunately it's with an issue.

It started last night during a 10 hour print: https://www.dropbox.com/s/sxryglbjkiq8eot/IMG_1632%20copy.jpg

As you can see, there are a few distorted layers and the piece broke in half when I removed it.

I re-calibrated the bed, tried a new print (http://www.thingiverse.com/thing:265525/#files) and again the same problem as you can see below:

print speed: 50mm/s

layer height: 0.1 mm

fill: 15%

Any thoughts on this?

Thank you

Thank you for you response.

Now that I know the name of the issue I can start searching for solutions. As for the temperature - I'm using the standard temperature profile for PLA (from the printer).

I've removed the white filament I was using and it seems there was a clog in the extruder - changing it cleaned it and I did a good print afterwards.

I will look for a solution to have the spool/loose filament somewhere below the printer as I see it's a popular way to avoid underextrusions.

Do different color filaments behave in different ways during printing? Matte versus translucent, white vs black ?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
